Is the word brigadeiro the same in Brazilian and European Portuguese?

No

The difference lies in the meaning of the word. In Brazilian Portuguese, a brigadeiro is a specific, iconic chocolate confection made from condensed milk, cocoa powder, and butter. In Continental Portuguese, brigadeiro refers to a military officer (a brigadier). While Portuguese people are aware of the Brazilian dessert due to cultural influence, the word itself does not function as a generic term for a chocolate sweet in Portugal; they would instead use terms like doce de chocolate or trufa.
